Baja_Costero said:In New Zealand that would be a northern exposure... to add to what others have noted, the plant needs more light. It should "see" the sun through the window for hours a day. Sometimes the exposure inside a window can be limited by its orientation or obstacles outside. The changes in this plant are a really good example of what happens to succulents in low light, for future reference, so you know what to look for down the road.
Regarding the ID question, there are a number of small knobby plants like that which can be hard to resolve for identification purposes until they flower. So I don't think you're necessarily going to come up with a firm name until you see flowers.
